Comparative study on anaesthetic management of trauma in canine patients using sevoflurane and isoflurane

Twenty four clinical cases of dogs having history of accidents irrespective of their age and sex were included in the study. Internal bleeding was diagnosed using ultrasonography and laparoscopy. The animals were divided randomly into 2 groups, viz. A and B, comprising 12 each. The animals were subjected to surgical intervention for the management of trauma with the anaesthetic protocol of atropine sulphate (0.04 mg/kg b.wt i.m.) and diazepam (1 mg/kg b.wt i.m.) (as premedication), and induction with thiopental sodium (10–12 mg/kg b.wt i.v.) followed by maintenance with either sevoflurane (3–3.5%) in group A or isoflurane (2–2.5%) in group B. The efficacy of anaesthetic combinations was determined by observing clinicophysiological parameters viz. onset and duration of anaesthesia, recovery time, pedal reflex, palpebral reflex, pharyngeal reflex, extent of salivation, heart rate, respiratory rate, respiratory minute volume and rectal temperature. On the basis of the observations, it was concluded that both combinations and provided cardiac and respiratory stability.
